Here is the problem
Both drive read CDs fine.
I can copy from both and read operations are normal.
I can't burn anything with the Plextor.

I made like a dozen costers so far.

It shiped w/ a Verbatim CDR and a Plextor CDRW cd.
I burned using Nero to the Verbatim at 24X
The operation completed sucessfuly under Nero.
Stick the CD into the Asus CD-ROM Can't read anything.
Stick the Burned CD into the Plextor Can't Read Anything.

I burned using Nero to the TDK at 12X
The operation completed sucessfuly under Nero.
Stick the CD into the Asus CD-ROM Can't read anything.
Stick the Burned CD into the Plextor Can't Read Anything.

I burned using Nero to the CDRW at 8X
The operation completed sucessfuly under Nero.
Stick the CD into the Asus CD-ROM Can't read anything.
Stick the Burned CD into the Plextor IT READS IT!

I tried to run the firmware update
PlexWriter 40/12/40 Firmware Upgrade Version 1.02
It fails just wont do it. Errors out everytime.
Is it supposed to work under XP?

Here is something you may want to check and change if true in your system. Make sure the Plextor drive is jumpered to MASTER and it is on the first IDE connector on the ribbon cable, and put the other drive on the end as slave.

IF that is not how it is set now you should switch it. I had a similar problem with my Liteon 48X12X48 when I tried to burn with it it would act like it is going to speed up and start but then it just paused and did nothing, and I it just repeated that cycle, until I rebooted. Afterward I switched the drives around and made the changes above and it worked flawless.

Yea I checked all the wiring and jumpers everything is good to go.
I even tried to make it the only drive on that IDE chanel took the CD reader completely off. That did not help either.
Anybody know why it would fail on the firmware update?

I did go to ASUS and patch every single driver for the a board. Just re-installed the SIS IDE Controller driver and yesterday did the ASPI update in the hope of flashing the Plextor which now I realize is allready on 1.02.... the latest and greatest. Hmmm....

POI mode. I was able to burn at 8X.

More like POS mode. This sucks. Ok I don't think I will be swaping motherboards I will probably get a scsi burner or another ATAPI Burner.
Not all burner have this problem with SIS?
What do you guys think.

Actually, PIO Mode is Programmed Input Output mode. It is an old method of transferring data from peripherals that requires that the CPU itself does the tranfer. Because of this, it is slow and inefficient.

the 16.6MB/s isn't a problem, that is fast enought for all burners.
the minus of PIO mode is that it uses a lot of the CPU. in DMA modes (Mult-Word DMA, UDMA) the CPU usage is much lower, and that is why you can burn at faster speeds.

like cfitz said, it's best to avoid PIO mode if you can. Multi-Word DMA is better, UDMA is best.

it think it came out in the other thread, that the SIS problem appears (apparently) only with Plextor drives or maybe just this model.

well I give up. It is a shame to because I really had my heart set on this plextor. I just hope the shop will be understanding and swap me another Burner to try.

After replacing the 40C cable w/ a new udma100 80c and

I'm back to PIO.
